COTTON-SEED LINTER.

Specification of Letters Patent.

Patented Mar, 27, 191'?.

Application filed July 28, 1914. Serial No. 353,598.

To all whom t may cof/wem:

Be it known that I, WILLIAM Il. Cox, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Cotton-Seed Linters, of which the following is a specification.

The present invention relates to improvements in cotton seed linters, and is designed especially as a de-linting machine which is more facile, economical, and efficient than many types of machines of this character now in use.

The primary object of the invention is to improve machines of this class by means of which the lint may be more thoroughly separated from the cotton seed after having passed through the cotton gin, and to more efficiently separate the lint from motes and other trash, thereby producing commercial' lint of a much higher quality.

The invention consists essentially in certain novel combinations and arrangements of parts by which the air is taken from in front of the linter and its passage to the linter regulated, and also in the disposition of the mote boards, as will be hereinafter described.

In the accompanying drawing I have illustrated one complete example of a linting machine equipped with the physical embodiment of my invention, constructed according to the best mode I have so far de'- vised for practical application of the principles of my invention.

In the typical linting machine illustrated in the drawing the casing 1 incloses the saw cylinder 2 which includes the usual gang of saws 3 passing between the ribs 4e, as will be readily understood by those skilled in the art. rlhe lint and seed are fed to the saws through the opening 5 from the hopper 6 and the float agitators 7 turn the seeds so that they pass down at the front of the saw cylinder and out througl'i the outlet opening 8 at the front of the casing.

The brush 9 revolving on its shaft 10 as indicated by the arrows carries the bristles 11 which contact with the cylinder 2 as usual. Preferably the brush revolves at a much higher rate of speed than the saw cylinder, and the cotton is brushed from the teeth of the saws down toward the floor or platform 12 through the chamber or space rIhe draft created by the revolution of the brush is the principal medium by Awhich the lint is drawn from the teeth of the saw cylinder, and a transversely extending plate 14 preferably of galvanized iron which extends from end to end vof the saw cylinder, is utilized to regulate the excess draft caused by the saw cylinder and deflect this draft down to a position within Vthe space 13 best suited to separate the trash and motes from the lint.

As before stated, the air for conveying the lint through the machine is brought in from in front of the linter. The air is brought in through the opening or doorway 15 in the front of the machine, and this opening or doorway is regulated as to size by means of the vertically adjustable gate or door 16, preferably of galvanized iron. Numerous ways may be adapted for guiding the door in its movement, but as an example I have illustrated slotted guide ways as 17 at each end of the door, and the door, which carries a rack wheel 18, may be raised or lowered by rotating this wheel in engagement with the stationary rack bar 19 at one side of the door. By this means the opening 15 may be regulated and the entrance of air to the casing of the machine may be governed. By locating the outlet for the seeds as 8 just above the entrance 15, any lint remaining on the seeds at this point will be carried into the linting ma chine by the draft, and thus saved for use.

An essential element of my invention is the mote board 20 which as clearly shown extends upwardly, at an angle, from the floor 12 and backward under the brush 9, passing within approximately two or three inches of the brush in actual use. At the rear this board merges into the wall 21 of a fiue 22 which opens adjacent the wire mesh drum 23 revolving as indicated by the arrow in proximity to the cylinder 24:.

This board is preferably of galvanized iron, and its location as shown prevents back draft `or drafts from the rear entering the linting machine, and the presence of this mote board as thus arranged eliminates the possibility of the dust that is deposited under the drum 23 from being carried back into the lint. The operation of the machine Will be evident. The loose lint, which falls in frontof the opening` 15 from the seeds passing through outlet 8, is carried through the opening 15 and together with the lint from the saw cylinder and brush, is passed through the flue 22 to the Wire mesh drum 23, the trash, etc., falls through the space 13, some of it striking the angular portion of the mote board 20 and being deposited yon the platform 12, and the dust falls beloW the Wire mesh drum Q3.

The loose lint from the seeds as they fall through the outlet 8, which ordinarily settles all over the lint room and linters and is swept up as trash and burned, is properly taken care of by passing through the opening 15 and is made into a merchantable product, and-the result is that the linters and lint room are almost free from dust and flying particles of lint. By the utili- Zation of my invention I not only secure a better and cleaner quality of lint, but more lint is secured because of the presence of the draft regulator and mote board 20.

Having thus fully described my inven- Copies of this patent may be obtained for tion, what I claim as new and desire to secure by Letters Patent 1s:-

1. The combination with a llntmg machine including the saw cylinder and brush i and casing therefor, of a mote board forming a space below these elements within the casing, adjustable means for permitting entrance through the front of the casing of' air to this space, and a transverse defiector plate between the cylinder and air inlet.

2. The combination in a linting machine With the saw cylinder, brush and casing, of amote board forming a space below the cylinder and brush and located below the brush to form a passage, said casing having an opening in its front and an :uljustable gate for regulating said opening, and :1 transverse dellector plate between saidopening and the cylinder.

In testimony whereof l alx my signature in presence of two witnesses.

WILLIAM H. COX.
